Magnetic amendment in the fabrication of environment friendly and biodegradable iron oxide/ethyl cellulose nanocomposite membrane via electrospinning

Flexible Methyl Cellulose/Polyaniline/Silver composite films with Enhanced Linear and Nonlinear Optical Properties

“…This increase was due to the creation of defect centers, which has led to a boost local polarizability. Moreover, the increase of (1) and (3) with increasing PANI and Ag contents has been attributed to the increase in the interaction of AgNPs with PANI/MC blend that resulted in an enhanced π-π* and n-π* transitions [51]. This result showed the advantages of fabrication composite films composed of PANI and AgNPs, which envisioned to enhance the absorption for the optical devices.…”

“…Currently, polymer composites are of high interest in different energy applications because of their pliable characteristics and their easy to use. [3]. Huge attention has been given to reveal the optical properties of polymers, and to potentiate their implementations in optical energy applications [4].…”

“…where P defines polarization of the material, (1) represents the linear susceptibility, (2) related to the second order NLO susceptibility which corresponding to a second harmonic generation, and ) (3) refer to the third order NLO susceptibility. Thus, it was possible to calculate the values of (1) and (3) by using the following relations (equations 20 and 21)…”

“…Where, no = n, because no >> n2. The change of (1) and (3) versus wavelength (λ) are depicted in Figs.17a and 17b, respectively of pristine MC, MC/1%PANI, MC/3%PANI, MC/3%PANI/0.5AgNPs and MC/3%PANI/1%AgNPs films. Notably, the values of (1) and (3) have increased with increasing both the PANI and AgNPs contents.…”

“…(a). Linear optical susceptibility (1) and (b) Non-linear optical susceptibility (3) as a function of wavelength (λ) of pristine MC, MC/1%PANI, MC/3%PANI, MC/3%PANI/0.5%Ag and MC/3%PANI/1%Ag films.…”
